Dear Russ,

I am very pleased to offer you the position of Senior Vice President, Chief Revenue Officer, based out of our Princeton, NJ office, reporting to me.

Your starting annualized base salary will be $300,000 payable on a semi-monthly basis. In addition to your base salary, subject to your signing the Model N variable compensation plan in effect for each fiscal year of your employment, you will be eligible to receive variable compensation in accordance with the applicable plan. Signing each year’s plan is a condition of your employment. We anticipate that your initial total targeted variable compensation on an annualized basis will be approximately $250,000, before taxes at 100% of achievement of your personal assignment under the Model N variable compensation plan for the current fiscal year, which will be sent to you following acceptance of this offer.

I will recommend to the Compensation Committee of our Board of Directors that you be granted Restricted Stock Units (“RSUs”) with a value of $550,000 USD and Performance-Based RSUs (“PB-RSUs”) with a value of $550,000 USD of Model N, Inc. through our Equity Incentive Plan. The RSUs are time based and vest over a four-year period with 25% vesting on each annual anniversary of the 15^th day of the second month of the quarter of your start date. The PB-RSUs vest over a three-year period with 50% vesting on the second and third annual anniversary of February 15, 2017.

In addition, I will also recommend to the Compensation Committee that you be granted additional RSUs with a value of $100,000 USD that vest over a three-month period commencing on February 15, 2017 with 100% vesting on May 15, 2017.

We will provide additional details on the three grants upon Compensation Committee approval.

In addition, as an employee of Model N, you will be eligible to participate in our Employee Stock Purchase Program (ESPP).   The ESPP offers employees the opportunity to purchase Model N stock at a 15% discount using post-tax payroll deductions. Enrollment into the program occurs twice a year in February and August.

You are also eligible for employee benefits starting on your first day. More information will be sent to you following acceptance of this offer.

As a Model N employee, you will be expected to sign and comply with an employee proprietary information and invention agreement which requires, among other provisions, confidentiality, the assignment of patentrights to any invention made during your employment at Model N and non-disclosure of proprietary information.

While you render services to Model N, you also will not assist any person or organization in competing with Model N, in preparing to compete with Model N, or in hiring any employees of Model N.
